4.0Release组件分析
[md]### 背景
**2023年11月，OpenHarmony如期而至的发布了4.0版本，开发套件同步升级到API 10。相比3.2 Release版本，新增4000多个API，应用开发能力更加丰富。虽然社区也同步发布了4.0的release报告（**[zh-cn/release-notes/OpenHarmony-v4.0-release.md · OpenHarmony/docs - Gitee.com](
https://gitee.com/openharmony/do ... ony-v4.0-release.md
)）也列了不少特性说明，对熟悉的人可能看的很清晰明了。此文章就做了个表格，从代码层面进行另一种解读。这是借助了社区的编译规范整改做的代码分析，基于的是4.0Release的源码

### 简单解读
* **分析范围**
**本次分析是通过对源码的分析构建的，主要分析的目录包括：base，device，drivers和foundation这四个目录，重点关注部件名称，代码描述，版本，组件，子系统，系统能力声明，依赖组件，依赖三方库。因为vendor，third\_party内容太多了，其他部分呢，属于应用、工具、内核等，不是本文重点关注的部分，所以没有加入分析范围。**
* **关注重点**
* **推荐的学习分析重点一个是版本，这表现了哪些组件有在4.0改动，哪些没有；**
* **依赖组件和依赖三方库是另外一个分析重点，这些标明了组件间的耦合关系；（这些是4.0开始整改的编译依赖内容，目前还有整改不完善的部分，在build仓里的whitelist里，文件里存在的就是还没整改完成的**
* **注意新名词，奤：ffrt，neural\_network\_runtime，intelligent\_voice\_framework；异构并发任务，神经网络运行时，智能语音服务框架。ffrt会逐步改变foundation的运行方式，**[
